UNHTEJD STATES PATENT QJFFHCCEO CARL T, SEVERSON, OF MINNEAPOLIS, MINNESOTA.

CARBONATING DEVICE.

Application filed. May 20,

To all whom it may concern Be it known that I, CARL J. SnvERsoN, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Carbonating Devices, of which the following is a specification.

The object of my invention is to provide a device by means of which water can be easily and quickly carbonated or charged with a carbonic acid gas without the use of a regular carbonating machine that is usually employed independently of the fountain.

A further object is to provide a device of simple, inexpensive construction and one which can be easily and quickly applied to a soda or soft drink fountain.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a sectional view through a carbonating device embodying my invention, the motor and valve being shown in full lines,

Figure 2 is a sectional view on the line 22 of Figure 1,

Figure 3 is a sectional view on the line 3-3 of Figure 1. 1

Figure 4 is an end view of a conventional fountain with my carbonating arm applied thereto,

Figure 5 is a front view of the controlling valve,

Figure 6 is a horizontal sectional View through the upper portion of the valve and the electric contacts mounted thereon,

Figure 7 is a vertical sectional view through the valve, showing the passages for the flow of the carbonated liquid therethrough,

Figure 8 is a sectional view on the line 8-8 of Figure 7,

Figure 9 is a fragmentary sectional view on the line 99 of Figure 7.

In the drawing, 2 represents the main body of the draft arm, having a base portion 3 and a threaded stud 4 for mounting the arm on the wall of the fountain. \Vithin this arm is a vertical chamber 5. A shaft 6 has Specification of Letters Patent.

a bearing in the lower end of said chamber and is revolved by suitable means such as an electric motor 7, that is mounted on suitable supports 8 on the top of the arm. This shaft 6 shown as a continuation of the shaft of the motor may be coupled therewith, if preferred. The motor support has preferably a threaded connection with the upper end of the arm.

, A series of blades 9 are mounted on the shaft 6 to revolve in the chamber 5 and thoroughly agitate the water and mix the gas therewith. A duct 10 is provided in the arm leading through the stud e for the delivery of gas to the upper part of the chamber and a similar duct 11 is arranged adjacent the duct 10 and delivers water to the top of the chamber. The exit from the chamber is the duct 12 communicating with the lower end of the chamber 5 and extending upwardly and forwardly in the arm 2, communicating with the discharge port in the valve 13. This valve is of ordinary construction, provided with an operating handle 14 and adapted to rotate in its socket in the arm and open or close the ports in the valve to the passage 12 and the discharge nozzle 15.

As shown in Figures 1 and 4, the valve is set in a neutral position with the ports closed. Contact surfaces 16 and 17 are provided on the casing of the valve for contact with the arm and when the arm is moved to engage the contact 16 the circuit will be closed through the conductor 18 to the motor and the conductors 19 to a suitable source of electrical energy in the usual way for making such connections. The motor will then be started and the revolution of the blades 9 will rapidly carbonate the water as it enters the chamber 5. When the liquid reaches the passage 12 it will be thoroughly mixed with the gas and be ready for delivery to the receptacle.

In Figure 4 I have shown myimproved carbonating arm mounted on a fountain 2 of any suitable design and connected as usual in soda fountains with a gas and water supply.

In carrying out the details of the electrical connections of the controlling valve, shown in Figure 1, I provide the curved operating handle 14 with contact points 14 carried by movement of the handle.

a conductor plate 145 that is insulated from the handle, preferably as shown. The contact surfaces 16 and 17 are connected with the feed and return conductors 18, as shown in Figures 1 and 6, an insulating or neutral surface being provided between the conducting surfaces. When the contacts 1 f ride on this neutral or insulating surface, as indicated by the position of the valve handle in Figure 2, the current will be broken through the motor but will be closed by movement of the operating handle in either direction to engage the contacts with either of the surfaces 16 or 17 to vary the character of the stream delivered.

The valve, herein shown in detail in Figures 7, 8 and 9, is of the ordinary wellknown construction used with fountains. The passage 12 leads into the head of the valve and a fixed washer 12 is mounted in said head and provided with a port 12 which communicates with the passage 12 and said Washer is also provided with similar ports 12 and 12. A block 13 is seated within a recess of the head and a clamping screw 13 is mounted in one end of the operating handle and engages said block to press it inwardly toward the washer 12 The block 13 has a passage 13 in register with the port 12 and one or the other of the ports 12 and 12 depending upon the position of the valve when the block 13 is rocked by The passage 13 registers alternately with the ports 12 and 12 of the fixed washer. The nozzle 15 of the valve has a spraying or distributing de vice 15 and ducts 15 and 15 are provided in the valve head leading from the ports 12 and 12 for directing the fluid at such an angle against the spraying device that a fine or coarse stream will be delivered, according to the angle of deflection. This is a well-known construction in valves of this type and I make no claim to the same herein, it being understood that the adjustment of the operating handle 14: on one contact surface will set the valve to deliver a certain stream and the movement of the operating handle to the other contact surface will also close the circuit but will change the position of the valve to deliver another stream, the

circuit being closed through the motor in both instances to operate the agitating device within the carbonating arm. This man ner of mounting the electrical connections and the motor may be modified in various ways within the scope of the appended claims, the essential feature of the invention being the location of the carbonating apparatus within the delivering arm instead of as usual employing an expensivecomplicated carbonating apparatus in the basement or in or near the fountain. One side of the arm is preferably provided with a pressure gauge 20 by means of which the attendant will be able to accurately determine the pressure of the liquid in the carbonating chamber.

I claim as my invention:

1. In combination, with a fountain, a hollo-w draft arm mounted thereon having a carbonating chamber therein, and inlet and discharge ducts for said chamber, an agitating device mounted in said chamber, or. an axis extending into the chamber, a motor attached to said axis on the exterior of the arm for operating said agitating device. and a fluid regulating means for said discharge duct,
